The maintenance of sub-domain information.To the maintenance of the sub-domain information of a certain top level domain using the common recognition of the authoritative node in TLD block chain
Cheng Shixian, the sub-domain information maintenance process of this decentralization are avoided because a certain network node is under attack or operation error
Whole system bring is influenced, the safety and stability of sub-domain information maintenance is improved, while also preventing believing subdomain
The malice of breath is distorted.
Either similar common recognition process is all made of (for example, knowing together using PoA in Root block chain or TLD block chain
Mechanism), specifically, the node on block chain is divided into two kinds of roles, authoritative node and ordinary node.Authoritative node can be packaged
Block simultaneously verifies signature to block, participates in common recognition process, and ordinary node only possesses the right of signature and forwarding.Authoritative node and
Ordinary node can be converted mutually, and initial authoritative node is served as by the domain name authority selected at random.In the follow-up process
When having new node addition, backup node is first served as, examines that nuclear energy is enough promoted as authoritative node through index after a period of time, this mistake
Journey is coordinated all quarters concerned to vote by the network identity multilateral coordination committee and be completed.If the node that carries weight is if there is confirmed makees vicious behaviour
For, it is also possible to it is downgraded to ordinary node and is even kicked out of.
The common recognition process of authoritative node including the following steps: (a) is determined by MOD operation with highest priority
Authoritative node；(b) when generating each block, each authoritative node all collects record, and simulation executes the domain name in a period of time
Operation note determines the reliability of source and legitimacy of each item record, abnormal record is marked；(c) node verification is remembered
After the completion of record, record is packaged into block, generates Correlation block information, including records Merkle tree root, deposit card Merkle tree root etc.；
(d) priority node has the right to take the lead in out block and to broadcast the new block of generation, and low priority node needs to wait for a period of time
Block could be broadcasted.If priority node cannot go out block in time, other vice-nodes just had the right to broadcast block at N seconds, continued
Common recognition process.Wherein, Fig. 2 is that authoritative node provided in this embodiment goes out block flow diagram, and referring to fig. 2, authoritative node is packaged
After the record information that each network node is collected, if the authoritative node is the authoritative node of highest priority, direct block out
(broadcasting immediately), otherwise, through going out block (delayed broadcasting) again after a period of time after waiting the authoritative node of highest priorities to go out block.
During common recognition, the authoritative node for receiving block information need to verify block information, verification process packet
Include: (a) all common recognition nodes verify block signature, block head, block chain content, by illegal area after receiving new block
Block abandons；(b) verifying of other nodes to this block is received simultaneously, it is true if receiving the confirmation more than 1/2 the whole network interstitial content
This fixed block is legal, and block chain is added, and executes the operation note in block, safeguards the consistent domain-name information state of each node.Its
In, Fig. 3 is the flow diagram that authoritative node provided in this embodiment verifies block, and referring to Fig. 3, authoritative node is receiving area
After block message, the signature, block head and block content of block information are verified, simply by the presence of verifying unacceptable content,
The block is then abandoned, otherwise, which is verified, verification result is broadcast to other each networks in block chain and is saved
Point.Table 1 is block head data structure table, and table 2 is that domain name records data structure table.

Further, described by first on the basis of the various embodiments described above for the common recognition process in Root block chain
First block information is broadcast to each second authoritative node by authoritative node, and receives pair sent by each second authoritative node
The verification result of first block information, if being more than first pre- to the authoritative node number that first block information is verified
If threshold value, then first block information is broadcast to each first network node, comprising:
The first authoritative node by highest priority in each authoritative node of Root block chain is wide by first block information
It is multicast to each second authoritative node, and receives the verification result to first block information sent by each second authoritative node,
If being more than the first preset threshold to the authoritative node number that first block information is verified, by first block information
It is broadcast to each first network node；
From first authoritative node first block information is broadcast to each second authoritative node after it is pre- by first
If the period, first block information is broadcast in each authoritative node of Root block chain by each second authoritative node, and
The verification result to first block information sent by each authoritative node of Root block chain is received, if to firstth area
The authoritative node number that block message is verified is more than first preset threshold, then first block information is broadcast to each the
One network node；
Wherein, in the identical authoritative node list of same block high maintenance of Root block chain.
Further, the first authoritative node of highest priority is selected by MOD operation in each authoritative node of Root block chain
Out.Algorithm for selecting the first authoritative node of highest priority need to guarantee that the selected probability of each authoritative node is equal, this
Embodiment does not limit specific algorithm.For example, calculating the block height and authoritative node of current Root block chain
Sum carries out the calculated result that MOD operation obtains, and the authoritative node that number is equal to the calculated result in authoritative node is determined as
First authoritative node of highest priority.For example, the first preset time period is 2s.
Further, for the common recognition process in TLD block chain, on the basis of the various embodiments described above,
Second block information is broadcast to each 4th authoritative node by third authoritative node, and is received by each 4th power
The verification result to second block information that prestige node is sent, if being saved to the authority that second block information is verified
Second block information is then broadcast to each second network node more than the second preset threshold by points, comprising:
Second block information is broadcasted by the third authoritative node of highest priority in each authoritative node of TLD block chain
To each 4th authoritative node, and the verification result to second block information sent by each 4th authoritative node is received, if
It is more than the second preset threshold to the authoritative node number that second block information is verified, then it is second block information is wide
It is multicast to each second network node；
From the third authoritative node second block information is broadcast to each 4th authoritative node after it is pre- by second
If the period, second block information is broadcast in each authoritative node of TLD block chain by tetra- authoritative node of You Ge, and is connect
The verification result to second block information sent by each authoritative node of TLD block chain is received, if to second block
The authoritative node number that Information Authentication passes through is more than second preset threshold, then second block information is broadcast to each second
Network node；
Wherein, in the identical authoritative node list of same block high maintenance of TLD block chain.
Further, the third authoritative node of highest priority is selected by MOD operation in each authoritative node of TLD block chain
Out.Algorithm for selecting the third authoritative node of highest priority need to guarantee that the selected probability of each authoritative node is equal, this
Embodiment does not limit specific algorithm.For example, calculate current TLD block chain block height and authoritative node it is total
Number carries out the calculated result that MOD operation obtains, and the authoritative node that number is equal to the calculated result in authoritative node is determined as excellent
The first highest third authoritative node of grade.For example, the second preset time period is 2s.
A kind of domain-name information maintenance system controlled altogether in many ways based on block chain is present embodiments provided, during common recognition,
Block is first gone out by the authoritative node of highest priority, block is gone out by remaining each authoritative node again after a period of time.This common recognition
Mechanism avoids the case where because that can not verify block information caused by when the authoritative node of highest priority can not go out block, maintains
System stability.
Block information is after common recognition process confirmation in the synchronous block information of each network node.Root chain corresponds to the area Root text
Part is safeguarded a root zone file by the registration office as node on chain jointly, and similarly, the node on each TLD chain safeguards one jointly
The area file of part TLD.The maintenance of each area file and the domain name operation note updated in foundation block chain in each block carry out
Real-time synchronization passes through one inspection of a period of time setting if being wherein likely present information inconsistence problems caused by delay
The function of point, assists each participant to keep the state consistency in the domain.The area file generated by block chain is as domain-name information
Trusted sources provide reliable information on services reliability for application layer, therefore, which, which does not change, existing user oriented and answers
Domain Name Services logic, the effect of block chain are only used for generating corresponding area file.
In order to which the data to block chain interior joint and transmission exercise supervision, then the polygon association of network identity is set up in Root block
The node where committee member is adjusted, sets up supervision node in TLD block chain.As shown in Figure 1, network identity is polygon in Root block chain
Coordinator node where the coordination committee.Coordinator node, which has, to be dominated to the voting process of authoritative node, to Root block chain
Each first network node exercises supervision, block information is exercised supervision and received to the progress of a certain network node with the presence or absence of abnormal
The effects of complaint.The network identity multilateral coordination committee is the neutral role in Root block chain, when each participant is in system layer
Face can not reach an agreement or the system failure in the case where, by the coordination of neutrality role, each side reaches an agreement again, maintenance system
System resumes operation.Supervision node, domain name data on synchronous chain, according to the policy in each domain and law to domain are added in TLD block chain
Name system is supervised.
It further, further include coordinating on the basis of the various embodiments described above, in Root block chain for Root block chain

There are the complaints of first problem node, then examine first problem node to each first network node broadcasts, and receive each first net
The response results whether first problem node is kicked out of to Root block chain that network node is sent, if response results are by first problem
The number of nodes that node kicks out of the first problem node of Root block chain is more than third predetermined threshold value, then each first network node is by the
One trouble node is kicked out of from the node listing of Root block chain.
Coordinator node can be detect abnormal block information after, first problem section is determined by abnormal block information
Point is also possible to directly determine that first problem node, the present embodiment do not do this specific limit by the behavior to network node
System.Third predetermined threshold value is the 1/2 of the first network node total number of Root block chain.That is, if being more than the first of half
The response results of network node are that first problem node kicked out of Root block chain, then the first problem node is from Root block chain
It kicks out of.
Further, for Root block chain, on the basis of the various embodiments described above, further includes:
Any first network node receives after the information that Root block chain adds the first newly-increased node, to Root block
Each first network node broadcasts first in chain increase node newly, and receive by each first network node sends whether by first newly
Increase the voting results that Root block chain is added in node, if agreeing to the first newly-increased node Root block chain is added in voting results
Number of nodes is more than the 4th preset threshold, then each first network node arranges the node that the first newly-increased node is added to Root block chain
In table.
4th preset threshold is the 1/2 of the first network node total number of Root block chain.That is, if being more than half
The voting results of first network node are that Root block chain is added in the first newly-increased node, then the first newly-increased node is added to
In Root block chain.
Present embodiments provide a kind of domain-name information maintenance system controlled altogether in many ways based on block chain, net in Root block chain
